The undersea archaeological department of the Indonesian Ministry of Culture and Tourism announced an investigation as rumours quickly circulated of 10 more such temples in the strait between Java and Bali. Excited local media speculated that an Atlantis of the East had been found.

Unfortunately, hopes of a groundbreaking discovery have been sunk. The city turns out to be an underwater theme park built by a British diver to entertain his customers.

Paul Turley, 43, "sank" the city in 2005 as an underwater attraction for visitors to his dive school in Pemuteran, north west Bali. He and an Australian colleague, Chris Brown, also aimed to highlight the importance of marine conservation.

Divers who visit the temple garden then make a donation to the Reef Gardeners project, where unemployed local fishermen are trained to maintain the corals close to the temple garden.

“When I heard about the story about a discovery in the news I had a good laugh,” said Mr Turley from Whitley Bay, Tyne and Wear, when contacted by the Daily Telegraph.

“We sank the temple garden as a fun idea and to do something different and the people that have dived it have loved it. Perhaps our publicity wasn’t good enough as no-one knew about it, but now I guess another great mystery has been solved.”

Photographs of the site have been posted on Mr Turley's website for years, but became the subject of feverish speculaton when they appeared this week on the social networking site Twitter. It appears that they were posted as a hoax.
